Roger Ronnie goes from engraving guns to making miniature versions of them

Roger holds the completed miniature 1896 Bergmann pistol. He restored the original and then made a duplicate at half size.

Rogerís second gun project was this half size 1910 Lefever ì$1000 Gradeî shotgun. It is shown with a miniature brass shotgun shell and reproductions of the original paperwork. An example of some of the extremely fine engraving and gold inlay work is shown on the trigger guard.

Roger Ronnie has been an engraver for over 30 years. His early training included gunsmithing school so he would know how to disassemble and repair the guns he would be engraving. However, he had never built a complete weapon from scratch until he took on the project to restore an 1896 Bergmann 6.5 mm pistol for a famous author. While he had the pistol apart he decided to duplicate every part at Ω size using his Sherline lathe and mill. Even the checkering on the grip is scaled down to half size and hand cut with a small file.

The Bergmann came out so nice he decided to attempt a more challenging project by building a Ω size version of a very rare 1910 Lefever ì$1000 Gradeî shotgun. For this project he had only photos that he had taken many years ago to work from. The ornate engraving of the original was quite a work of art at full size, but reproducing it at half size was extraordinarily difficult. As you can see, Roger did a masterful job. His latest project is now a Sharps Borchard rifle. More on Rogerís work can be seen at

Shop Tip of the month:

Tailstock gib quick adjustment screws and locking lever by Brian James

Knurled adjustment screws and a shortened hex key make quick work of tailstock adjustment. (Click on photo for larger image)

Brian James of Amsterdam sent the above photo of his solution to being able to quickly remove and/or readjust the tailstock. First, he replaced the two attachment screws that hold the brass gib to the tailstock, saying he found it time-consuming and difficult to adjust them from below with a hex key. He made custom knurled screws that can be adjusted and tightened with no tools other than your fingers. (They are then locked in place from above with the set screws just like before.) Also you will notice that he has shortened a 5/32" hex key and left it in place in the locking screw that secures the tailstock in place. This saves fishing around for one every time you need to move the tailstock. The shorter wrench still provides plenty of leverage for tightening, and lessens the chance of over-tightening. Exact dimensions are not critical on these parts, and the photo should be enough to get you started with a similar modification of your own should you choose to add this to your lathe.

Extended travel 15" mill column and 18" table

Photos show the longer P/N 45260 mill column (left) and P/N 54182 table (right) with a typical accompanying leadscrew. Leadscrews are purchased separately based on your application (inch or metric, manual or CNC). (Call or see the replacement parts list for part numbers.)

Sherline customers often ask how they can increase the capacity of their milling machines. This year we introduced two new replacement parts that make it possible to add 4" to the Z-axis travel of any Sherline mill and 5" to the length and travel of the mill table.

P/N 45260 15" mill column bed ($90.00). Leadscrews are $18.00 each and are available in inch or metric, manual or CNC versions.

P/N 54182 18" mill table ($185.00). Leadscrews are $40 each and are available in inch or metric, manual or CNC versions.

New machines can also be special ordered with these parts already installed. The additional cost is $90.00 for the 15" column bed and $185.00 for the 18" table. The appropriate leadscrews are included at no extra charge when ordered as part of a new mill. Call Sherline direct at (800) 541-0735 to order these as factory installed options, or the parts themselves are available at

ï A new YouTube video has just been created that takes you on a tour of the museum in Vista, CA. The 7-1/2 minute video shows the various rooms of the museum and highlights a few of the best projects. Tom Boyer fires up the Seal engine too. The quality of video on YouTube doesnít do justice to the fine craftsmanship shown, but hopefully it will inspire a few of you to add the museum to their ìmust seeî list when visiting Southern California. See the video at

ï The newest addition to the on-line museum is boat builder Fred Heim of Marlborough, MA. As a hobby Fred makes wood models of construction equipment in an unusual scale. While most modelers work with an easy-to-handle small size, Fred models big pieces like a Peterbilt truck and Caterpillar crawlers in a huge half scale. See Fredís page at
